Trump is on the second day of a 12-day Asian trip that is focusing on both trade and North Korea's nuclear missile programmes.
Abe told the same news conference that Japan backed Trump's stance that “all options” are on the table when it comes to North Korea, saying the two countries were “100 percent” together on the issue.
Earlier, Trump vowed to push for a free and balanced trade partnership with Japan after decades of “massive trade deficits” but said relations with close ally Tokyo were “better than we have ever had”.
Abe, at the start of a working lunch with Trump, offered his “heart-felt condolences” for the victims of a gunman who massacred at least 26 worshippers at a church in Texas.
White House spokeswoman Sarah Sanders said Trump, who earlier expressed grief for the victims, had no plans at this time to change the schedule for his 12-day Asian trip, which will also take him to Seoul, Beijing and Danang, Vietnam.
